Description
Technical field
The utility model belongs to technical field of mold, more particularly, relates to a kind of silicon gel injection forming mould.
Background technology
Injection mo(u)lding is meant plastics melted by heating in the heating cylinder of injection machine earlier, then under the promotion of screw in injection molding machine or piston, through the running gate system entering mold cavity of nozzle and mould, sclerosis typing in die cavity at last.Here it is injection molding simple procedure, and the used mould of injection mo(u)lding just is injection forming mold.Injection mold is mainly used in the moulding of thermoplastic articles, but also more and more in recent years moulding that is used for thermosetting plastics.Injection mo(u)lding occupies great ratio in the moulding of plastic products, thereby to have a greater part of in the production of mould for plastics approximately all be injection mold.
The engine high pressure igniter mainly is that the protection high-voltage spark exposes with the spark plug sheath, if protection failure is prone to cause problems such as engine is on fire.The design feature of this product is that goods are carefully grown, and complex-shaped, dimensional requirement is high.But since this performance of products and style characteristic, the mould structures that adopt horizontal or vertical notes to press of production mould in the past more, mould pickup number is few, and Mould operation is complicated, goods cure time long (about 10 minutes), production efficiency is low.Past has the colleague to attempt with vertical Kazakhstan furan injecting molding die structure, but owing to capturing or the equidistant design of cognitive injection flow passage, and product exists starved, incipient scorch, tear and fail.
Summary of the invention
The technical problem that solves
Deficiency to prior art; Design feature with reference to injection molding of rubber; The utility model has carried out the improvement and the innovation of mould and injection flow passage thereof, improves a kind of silicon gel injection forming mould, and it has solved the nonsynchronous problem of multi-cavity moment injecting glue; Guarantee product quality, improved production efficiency.
Technical scheme
Die feature of the utility model and principle:
Sizing material passes through the squeezing action of interior heat of injection (mo(u)lding) machine and screw rod, the plasticity increase, and viscosity descends, flowing velocity quickening, entering mould, the sizing material synchronous die cavity that injects core rod and Kazakhstan furan mould formation of moment of process rebound and runner plate.Because the sizing material flowing velocity is fast; So it is even to get into the sizing material plasticizing of die cavity; Sizing material temperature under the viscous state is pressed about the high 20 ° of C of filler with annotating than common mold pressing filler again, and then the temperature of sizing material is even, in case after going up the pressure locked mode; Rubber arrives crosslinking temperature immediately, so the time of sulfuration can shorten to 4.5 minutes from 9 minutes.Again because the design of the symmetrical structure of runner can make the interior sizing material of die cavity realize synchronic curing.
The purpose of the utility model realizes through following technical scheme:
A kind of silicon gel injection forming mould, it comprises mould, core rod, counterdie in rebound, runner plate, patrix, the Kazakhstan furan; Said counterdie is fixed on the following hot plate of injection (mo(u)lding) machine, and said core rod is fixed in the groove of counterdie, and mould is nested in the groove of counterdie and is enclosed within the periphery of said core rod in the furan of said Kazakhstan; Said patrix is fixed on the top of said counterdie, and said runner plate is connected in the top of patrix, and said runner plate is provided with cast gate, and sizing material injects from cast gate; Said core rod passes from bottom to up successively to be breathed out in the furan mould, patrix and stretches in the cast gate of runner plate, core rod with breathe out that the space between mould, the patrix forms sizing material injection die cavity in the furan, sizing material is from the injection of the cast gate between core rod and runner plate die cavity; Said rebound is positioned at the top of runner plate, and is fixed on the last hot plate of injection (mo(u)lding) machine.
About injection molding channel structure on the described runner plate is, the left-right symmetric structure, about the end of said injection molding channel structure, about the symmetrical cast gate that distributed.The end symmetrical of said injection molding channel structure 32 cast gates that distributed.Such symmetrical structure is to equate for the distance that makes the sizing material inlet arrive each cast gate; Can guarantee evenly synchronous each die cavity of injection of sizing material in the moment of injecting glue; Make the interior sizing material of the die cavity that is distributed in each position of mould realize synchronic curing; Make the density of every chamber goods consistent, state of cure (vulcanization) is consistent, guarantees every chamber properties of product, the uniformity of dimensional contraction, stability.
Described injection molding channel structure comprises two first straight channel, and the junction of said two first straight channel is provided with the sizing material inlet, and sizing material gets into said injection molding channel structure from described sizing material inlet; The said first straight channel end evenly is divided into two branch flow passages and is smoothly transitted into two first arc runners; The said first arc flow field end is provided with a circular buffer part; Said circular buffer part and two second arc runners join; Each end of the said second arc runner evenly is divided into two branch flow passages and seamlessly transits with two second straight channel and joins; The end of each second straight channel and the cast gate that is connected an injection moulding respectively, sizing material gets into core rod and the sizing material injection die cavity of breathing out mould in the furan, patrix formation through said cast gate.
The face area of said first straight channel is greater than the face area of the first arc runner; The face area of the said first arc runner is greater than the face area of the second arc runner, and the face area of the said second arc runner is greater than the face area of second straight channel.It is smooth and easy and mobile apace in runner in order to guarantee sizing material that such runner face size relates to.
Sizing material gets in the injection molding channel structure of runner plate through the sizing material inlet; First straight channel, the first arc runner of flowing through successively on the runner plate arrive circular buffer part; The sizing material of circular buffer part flow to second straight channel through the second arc runner again; Finally flow into each cast gate through second straight channel, sizing material gets into core rod and the sizing material injection die cavity of breathing out mould the furan, patrix formation from cast gate.
Beneficial effect
Than prior art, the beneficial effect of the utility model mould structure is:
(1) the utility model has changed the low and not high problem of product percent of pass of the number of the mould pickup in the past inconsistent production capacities that cause of density few and each die cavity goods.The runner design of the utility model; Through detailed calculating and sunykatuib analysis; Can guarantee evenly synchronous each die cavity of injection of sizing material in the moment of injecting glue, make to be distributed in the synchronic curing that mould is given sizing material in the die cavity at position, make the density of every chamber goods consistent; State of cure (vulcanization) is consistent, guarantees every chamber properties of product, the uniformity of dimensional contraction, stability;
